Increase partition size

[emediaboard]

This question relates to a totally unknown area of LINUX for me... partitions.
I have installed a while back Debian Squeeze of a sheevaplug. The system can accept SSD cards as external drives and treats them as SCSI. To clone these cards I am using protocol based on dd and bzip/bunzip.

I have cloned a 4GB card to a 16GB card and my new clone works exactly as the original.

Problem is... I have 12GB totally unknown. Using webmin I see:

SCSI device B
Disk size: 15.03 GB | Make and model: Myson SD/MMC/MS Reader | Cylinders: 15387 | Partition format: MSDOS

When I look at the partition #2, the one I want to extend I see the size is (correctly 3.39 GB).

I have fsck /dev/sdb2 and I have tried to use resize2fs but this tells me all the available space is used... it doen't recognize the "empty" space on that drive.

Is there another way I should use to be able to extend sdb2 as I don't want to create a new partition? Thanks.

Hello emediaboard!

It might help if you can post the output of:

$ fdisk -l (l is a lower case L)

/dev/sdb2 is the one I want to increase

I was going to try fdisk....

Thank you!

I hope the gurus can take a look at this and give you some advise on how to proceed. I'm bumping this up for some chance of visibility!

Good luck!

Hi there.

You should be able to use a tool such as Parted Magic or GParted to accomplish what you need.
